PJBLOG超文本链接实现彩虹变幻效果
超级链接彩虹效果,就是当鼠标经过超级链接时,超级链接一直不停的变幻彩色
首先新建一个文件取名为“rainbow.js”,加入如下代码并上传到PJBLOG根目录:
var rate = 20;
var obj;
var act = 0;
var elmH = 0;
var elmS = 128;
var elmV = 255;
var clrOrg;
var TimerID;
if (navigator.appName.indexOf("Microsoft",0) != -1 &&
parseInt(navigator.appVersion) >= 4) {
Browser = true;
} else {
Browser = false;
}
if (Browser) {
document.onmouseover = doRainbowAnchor;
document.onmouseout = stopRainbowAnchor;
}
function doRainbow()
{
if (Browser && act != 1) {
act = 1;
obj = event.srcElement;
clrOrg = obj.style.color;
TimerID = setInterval("ChangeColor()",100);
}
}
function stopRainbow()
{
if (Browser && act != 0) {
obj.style.color = clrOrg;
clearInterval(TimerID);
act = 0;
}
}
function doRainbowAnchor()
{
if (Browser && act != 1) {
obj = event.srcElement;
if (obj.tagName == 'A' && obj.href != '') {
act = 1;
clrOrg = obj.style.color;
TimerID = setInterval("ChangeColor()",100);
}
}
}
function stopRainbowAnchor()
{
if (Browser && act != 0) {
if (obj.tagName == 'A') {
obj.style.color = clrOrg;
clearInterval(TimerID);
act = 0;
}
}
}
function ChangeColor()
{
obj.style.color = makeColor();
}
function makeColor()
{
if (elmS == 0) {
elmR = elmV; elmG = elmV; elmB = elmV;
}
else {
t1 = elmV;
t2 = (255 - elmS) * elmV / 255;
t3 = elmH % 60;
t3 = (t1 - t2) * t3 / 60;
if (elmH < 60) {
elmR = t1; elmB = t2; elmG = t2 + t3;
}
else if (elmH < 120) {
elmG = t1; elmB = t2; elmR = t1 - t3;
}
else if (elmH < 180) {
elmG = t1; elmR = t2; elmB = t2 + t3;
}
else if (elmH < 240) {
elmB = t1; elmR = t2; elmG = t1 - t3;
}
else if (elmH < 300) {
elmB = t1; elmG = t2; elmR = t2 + t3;
}
else if (elmH < 360) {
elmR = t1; elmG = t2; elmB = t1 - t3;
}
else {
elmR = 0; elmG = 0; elmB = 0;
}
}
elmR = Math.floor(elmR);
elmG = Math.floor(elmG);
elmB = Math.floor(elmB);
clrRGB = '#' + elmR.toString(16) + elmG.toString(16) + elmB.toString(16);
elmH = elmH + rate;
if (elmH >= 360)
elmH = 0;
return clrRGB;
}
提醒一句:一定要保存为utf-8编码
然后打开header.asp,找到
<script type="text/javascript" src="common/common.js"></script>
在其后面添加如下代码:
<script type="text/javascript" src="rainbow.js"></script>

彩虹渐变效果如下:
鼠标放在具有超链接属性的字符上时,这段文字的色彩渐变效果
现在就来介绍一下这个效果的具体实现步骤:
首先,新建一个文本文档,例如取名为href,后缀为.htc。
在文档中写入以下内容:
<public:component>
<public:attach event="onmouseover" onevent="domouseover()">
<public:attach event="onmouseout" onevent="domouseout()">
<script language="javascript">
function domouseover(){
with(element)
{filters.item(0).Apply();filters.item(0).Play();}}
function domouseout(){
with(element){
filters.item(0).Apply();
filters.item(0).Play();}}
</script>
</public:component>
打开已经设置好超链接的网页,在<head></head>之间写入以下内容(或者你也可以直接修改你的css文件):
<styl
